AUTOMATIC FILLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 520,557, dated May 29,1894. Application filed JuneZ9,189 5 Serial No. 479,177. (No model.)

To all whom it may concern:

l 3e it known that I, ARTHUR E. BRIGGS, a citizen of the United Statesof America, residing-at Bond Hill, in the county of Hamilton and Stateof Ohio, have invented a new and useful Improvement in Automatic FillingDe- 27 1085, of which the following is a specifica- My invention relatesto apparatus for fill- 1ng liquid receptacles, and the object is toprovide mechanism which will automatically cut oi the fiow of theliquidwhen the receivng vessel is filled to the required limit, and itconsists in the parts and combination and arrangement of partshereinafter described and claimed.

In the drawings: Figure 1 is a perspective vlew of my improved fillingdevice as used for filling bottles. Fig. 2 is aside view, partly insection, showing the cut-01f valve open. Fig. 3 is a like view showingthe valve closed.

The valve casing consists of sections Aand A, one of which is providedwith an inlet aperture a and the other with adischarge spout a. Thespout is provided with a lateral opening a for the discharge of theliquid. The section A has an internal annular shoulder a forming a seatfor a partition B, and the portion above the shoulder is threaded toreceive a threaded rim on the section A. The partition B is providedwith an aperture b for the passage of the liquid,the How of which iscontrolled by a valve 0, mounted. on a valve stem 0 taking through theaperture and having its bearings in a bracket 1) in front of thepartition and in an arm cl depending from a bracket D secured to theback of th partition.

E is an escapement pivoted at e and having an arm e adapted to engage anotch fin the lever F, pivoted at cl to the bracket D and normallyholding the escapement in a raised position.

G is a gravitating pawl pivoted to a depending arm (1 adapted to engagewith a notch e in the escapement and limited in its swing when releasedby a lug 6 H is a push pin mounted in a bearing a in the wall of thecasing and bearing against the valve 0.

I is a float serving as a piston adapted to I reciprocate in the lowerend of the discharge spout, provided with a piston-rod *6 extending upinto the valve casing and guided therein by the bearing block a andadapted to raise the lever F.

The valve stem 0 takes through a slot e in the arm e. Its inner endtakes against the pawl G and is provided with an enlargement or collar 0adapted to engage with and actuate the arm e. The valve 0 is normallyheld to its seat by a spring 0 J is a stop adjustable along thedischarge spout and adapted to hold the latter at any desired elevationin the bottle or other vessel to be filled. The form shown is an elasticband.

K is a flexible tube adapted to serve as a siphon.

The operationis as follows: When the liquid is to be withdrawn, theinlet aperture is connected with the tube K, which is preferablyfiexible, and the latter is inserted into the cask or other vessel fromwhich the liquid is to be withdrawn; the valve 0 is opened by means ofthepush pin H; the pawl G, which has been held up by the valve stem, isreleased and drops; the arm 6 isforced inward by the collar on the valvestem thereby raising the escapement E. When the arm ef reaches the notchfin lever F the escapement is in its locking position and the leverdrops, thereby locking the arm 6 in position. A vacuum is then formed bysucking the air from the casing, the valve is closed and the dischargetube inserted inthe vessel to be filled. The valve is again opened. bymeans of the push pin allowing the liquid to flow. As the liquid in thereceiving vessel approaches the desired limit it lifts the float I andthereby raises the piston rod 2' which lifts the lever F and releasesthe arm 6'. The escapement then drops thereby releasing pawl G and thevalve is closed by the action of thespring 0 The piston float may bemade to operate at any predetermined point by adjusting the collar J onthe spout and thereby regulating the depth to which the spout extendsinto the vessel.

What I claim is-= 1. In a filling device, the combination of a valvecasing; a valve seated therein; means of the valve whereby the valve maybe operated; mechanism in the valve casing for looking the valve in itsopen position, and means for releasing the locking mechanism,substantially as and for the purpose specified.

3. In afilling device, the combination of a valve casing; a valvetherein yieldingly held to i'ts seat; avalve stem; a push-pin for actu"ating the valve; a pawl for locking the valve stem normally held out ofengagement thereby; an escapement adapted to be thrown into engagementwith the pawl by' the movement of the valve stem; a lever adapted tolock the escapem-ent in position for holdingthe pawl against-thepressure of the valve stem, and means for releasing'the lockingmechanism, substantiallyas and for the purpose specified.

4:. "In a fillingdevice, the combination of a valve casing; a valveyieldingly held to its seat; a discharge spout extending from the valvecasing; a push-pin projecting through the casing and adapted to bearagainst the face of the valve whereby the valve may be opened; mechanismconsisting of a pawl, escapement and lever for locking the valve in itsopen position; a float in the discharge spout and mechanism actuatedthereby for releasing the locking mechanism, substantially-as :and forthe purpose specified.

5. In a fi'lling device, the-combination of a valve casing; a valvetherein yieldingly held to it-sseat; a valve stem; a push-pinforactuati-ng the valve; a pawl for locking the valve stem normally heldout of engagement thereby; an escapement adapted to bethrown intoengagement with the pawl by the movement of the valve stem as the valveopens; a lever adapted to lock the escapement in position for holdingthe pawl against the pressureof the valve stem; a discharge spout; afloat adapted to reciprocate therein, and a rod extending from the floatadapted to actuate the lever and disengage the escapement, substantiallyas and for the purpose specified.

6. In a filling device, the combination of a valve casing; a valvetherein yieldingly held to its seat; a valve stem; a push-pin foractuating the valve; a pawl for locking the valve stem'normally held outof engagement thereby; an escapement adapted to be thrown intoengagement with .the pawl by the movement of the valve stem as thevalveopensia lever ture b; a valve 0 for closing the aperturepro videdwith a valve stem 0 having a-collarc; a spring 0 for normally holdingthevalve to its seat; .a push-pin I-Iforactuating the valve; a pawlG'forlocking the valve stem; -.an escapemen-t provided with an arm e forlocking the pawl; a lever -F for locking the escapement; a dischargespout a; a :float I adapted to reciprocate therein; a rod 5 connected tothe float and adapted to actuate lever F, substantially as and for thepurpose specified.
